COLLAPSIBLE BRACKET Application filed September 21, 1928.

My invention relates to improvements in collapsible brackets.

An important object of my invention is to provide a bracket of this character which 5 is of simple and practical construction, is strong and durable, and which may be easily and quickly collapsed or disfolded from the extended position, and which is neat and attractive in appearance, and otherwise well 10 adapted for the purposes for which the same is intended.

Another important object of my invention is to provide a bracket of the type described which can be securely locked in extended position. 7

Other objects and advantages of the invention will be apparent during the course of the following description:

In the accompanying drawing, forming a 20 part of this application and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a side elevation of a bracket embodying my invention.

Figure 2 is a bottom plan View of Fig. 1, and

Figure 3 is a perspective view of one of the attaching plates.

Figure 4 is side elevational 718W of my bracket in folded position and applied so as to join two movable objects, such as are shown in section.

Referring now to the drawing in detail the invention comprises a collapsible bracket adapted for attaching to the sections of a folding article, such as a wagon tongue or the like, indicated generally at A. Attaching plates 5 are secured to the folding sections. Each plate 5 is provided with an angular extension 6 having one side cast with hearing lug 7 bored as indicated at 8.

The bracket per se is composed of the arms 9 and 10. The arm 9 has a split bearing member 11 at one end between the furcations of which the bearing lug 7 is received. hinge pin 12 is projected through the hearing member 11 and the lug 7 By this arrangement, movement of the arm 9 is stopped by the angular extension 6 as seen in Fig. 1. At the remaining end of the arm 9 is another split bearing 13.

The same end of the arm 9 is provided with an offset longitudinal extension 14, provided in one face with a recess 15.

The arm 10 is formed at its outward end with a split bearing member 11 between the furcations of which the associated attaching plate is inward end of bearing lug 7 on the received. The provided with the arm is a single bearing member 16 receivable between the furcations of the bearing member 13 on the inward end of the arm 9.

The inward end of the arm 10 is provided in addition with a curved or concaved or otherwise formed 17 and at a distance from the end of the arm 10 thereis a screw threaded bore 18.

The arms are assembled to the attaching plates,

plates, for the arms.

as stated, by passing hinge pins 12 thru the bearing members 11 of the arms and through the bearing so that the extensions lugs 7 of the attaching 6 act as stops The arms are assembled in hinged relation by placing the bearing member 16 between the bearing member 13, on arm 9 and passing a the furcations and the When so assembled, the extension 14 end of the arm 10 as ber. overlaps the seen in Fig.

inward 1.

furcations of the split the inward end of the hinge pin 19 through single bearing mem- At the same time, the angularly related surface 17 at the inward end of the arm 10 is engaged with the ad acent surface of the bearing members 13, as seen also in Fig. 1.

The shape of the angularly related surface is to be conformed with the shape of the member which it is disposed to engage.

In the position of the arms 9 and 10 shown in Fig. 1, a thumb screw 20, having a hearing flange or washer 21 adapted for engagement w1th the ad acent surface of the extension 14, is passed through the extension 14 and through A into the threaded bore 18 in the arm 10. R0-

the recess and is threaded tation of the screw in the tightening direction will clamp bracket described shoWn in Fig. 1

A pin 22 or the various parts of the rigidly 1n the positions the like is secured to a porangularly related surface tion of the screw within the recess 15 to maintain the screw against falling from the arm 9 when the screw is not engaged with the arm 10, as when the bracket is folded or collapsed. A collapsed position of my bracket is shown in Fig. 4, wherein it is shown attached to movable sections of a structure such as a collapsible wagon tongue, a collapsible automobile top, a collapsible chair or table, collapsible shell, and the like.

It is to-be understood that the form of my invention herewith shown and described is to be taken as a preferred embodiment of the-same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the a subjoined claims.

i scribed comprising a mainarm,

of the arms also as thereon, pins at the ends Having thus described my invention what I claim as new is:

1. A collapsible bracket comprising a pair of arms having bearing means formed at each end, attaching plates at the outer ends having bearing means of the arms for pivotally connecting the inner ends thereof to each other and for pivotally connecting the outer ends of the arms to said plates, an extension formed at the inner end of one of the arms for overlapping the other of said arms, a thumb screw threaded through the extension and the overlapped arm, a pin disposed transversely of the screw and dis posed at the from the extension and a recess formed in the extension to accommodate the transverse pin to enable the close engagement of the extension with the overlapped arm to form a stop for said arm.- 7

2. A collapsible bracket of the type dea split eye formed to depend from the outer end of the main arm, and a support bracket carryextension on the main arm,

- I side of the extension opposite ,from' the head of the screw whereby to pre- 1 vent separation of the screw the innerendvofth'e' main arm, and a pivot pin through said split eye and said solid eye; and a thumb screw having its shank passed through a vertical aperture in the the upper surface of saidextension having a recess concentric with said aperture, and a pin extendingfrom the shank of the thumb to prevent the thumb screw from fallin out of the aperture, and the end of the said shank adapted to screw thread into a screw threaded vertical hole in the inner end porscrew tion of the secondary arm, for positively preventing movement of the arms.
